Squamous Cell Carcinoma (SCC)
Squamous cell carcinoma (SCC) is a locally invasive malignant tumor that arises from a cell type known as the keratinocyte or also known as squamous cell, the primary cell type found in the skin and mucous membranes.
Despite their common cell of origin, SCC tumors display different characteristics in dogs and cats, among them prevalence, preferred sites, behavior, environmental influences, and genetic predisposition.
It is classified by its location in the skin (cutaneous), mouth (oral), or nailbeds (subungual). In the mouth, the gum, tongue, or tonsils are most prone. Also affected at the temples, the outer tips of the ears (pinnae), the eyelids, the lips, and the nasal planum (tip of the nose). In the skin, locations that are less pigmented, lack hair, or are sparsely-haired are most typically affected. An internal form that affects the liver or lungs is considered much less common.
SCCs are common tumors of dogs and cats. They vary in appearance, location, and biological behavior; however, they are typically locally aggressive, with a reported low to moderate metastatic potential. Early recognition, diagnosis, and treatment are essential.
